✦ Synopsis

Rate constants are reported for the state-specific vibrational relaxation of O2 (8 d v< 11) by NOz and O2 at 295 K. O2 is formed in vibrational levels up to II= 11 by the reaction of 0( 3P) atoms with NO1. The oxygen atoms were created by partial photolysis of NOz at 355 nm using a frequency-tripled Nd : YAG laser, and the kinetics of O2 in particular v levels observed by laser-induced fluorescence in the (0, u) bands of the B 3Z; -X3x; system. The rate constants for relaxation of O2 by NOz, in units of IO-
